Lip seals is widely used in heating and ventilation application, such as gas boiler.

After technical and application discussion with a European customer, who is one of the biggest suppliers of heating system, we design a new constructure and choose both EPDM and Silicone material for different sealing positions. Considering to the risk of test, we suggest a pilot tool produce samples for test. Thanks to the work of our team, the samples passed the test.
